PURPOSE:The titled rolling oil, obtained by adding a specific lower fatty acid to an oil consisting of a synthetic ester, an animal or vegetable fat or oil as a base oil, capable of improving the smoothing abrasion resitance, and suitable for continuous casting under high-speed rolling conditions of a high-pressure load. CONSTITUTION:A rolling oil obtained by adding (B) 1-10% 6-10C lower fatty acid, e.g. caproic acid, to (A) an oil, consisting of (i) a synthetic ester, e.g. methyl stearate, or/and (ii) an animal or vegetable fat or oil, e.g. beef tallow or palm oil, and having <=15cst viscosity at 50 deg.C as a base oil. EFFECT:Slip caused by friction of work rolls and chattering induced thereby will scarcely occur, and the roll abrasion resistance is good with a stabilized friction coefficient in roll bites. |
